Document Type and Number:
WIPO Patent Application WO/2022/222300
Kind Code:
A1
Abstract:
The present application relates to artificial intelligence technology, and discloses an open relationship extraction method, comprising: obtaining an original training set by using remote supervision and entity linking techniques; performing policy annotation and entity reinforcement processing on the original training set to obtain a standard training set; using the standard training set to perform entity fine adjustment and relationship fine adjustment on a pre-trained language model to obtain an open entity extraction model and an open relationship extraction model; extracting, by using the open entity extraction model, entities in a text to be classified; and predicting an entity relationship between the entities by using the open relationship extraction model, and clustering the entities and the entity relationship to obtain a relationship extraction result. In addition, the present application further relates to blockchain technology, and the relationship extraction result may be stored in a node of a blockchain. The present application further provides an open relationship extraction apparatus, an electronic device, and a computer-readable storage medium. The present application can solve the problem of relatively low extraction efficiency of an open relationship.
